<!-- Configure tcp buffer sizes in the form:
rmem_min,rmem_def,rmem_max,wmem_min,wmem_def,wmem_max
If this is configured as an empty string, the system default will be applied.
For now this config is used by mobile data only. In the future it should be
used by Wi-Fi as well.
Note that starting from Android 13, the TCP buffer size is fixed after boot up, and should
never be changed based on carriers or the network types. The value should be configured
appropriately based on the device's memory and performance. It is recommended to use lower
values if the device has low memory or doesn't support high-speed network such like LTE,
NR, or Wifi.
